A quarter-century of managed security, built inside a hundred-year industrial company - watching threats across five Security Operations Centers, 24/7/365.
Hitachi Cyber is the global managed-security arm of the Hitachi Group. Legally it is Hitachi Systems Trusted Cyber Management Inc.; commercially, since 2024, it goes to market under one name. Its job is unglamorous and constant: watch client networks around the clock, catch the intrusions that matter, and shorten the gap between a threat appearing and someone stopping it.
The company is not a startup and not a pure reseller. Its roots reach back to 1999, when the security business was founded in Blainville, Quebec. A separate analytics company, Cumulus Systems, was incorporated in 2006, acquired by Hitachi in 2012, and later merged with the security business. In 2022 the combined entity was renamed Hitachi Systems Trusted Cyber Management, and in 2024 everything unified under the Hitachi Cyber brand. That history explains an unusual dual identity - it sells both cybersecurity services and performance-analytics tooling.
The work sits on four pillars: 24/7 managed security services, cyber threat intelligence, governance-risk-and-compliance advisory, and performance analytics. Behind them runs a distributed network of Security Operations Centers that hand monitoring off across time zones so coverage never lapses.
More than 350 private and government-owned organizations rely on Hitachi Cyber, concentrated in the industries where downtime is expensive and failure is public: energy, manufacturing, transportation, financial services, healthcare, government and IT services.
The problem it addresses is structural. Most organizations cannot staff a 24-hour security team, cannot keep pace with alert volume, and cannot tell a genuine intrusion from noise fast enough. Tools alone do not solve this - a SIEM without analysts is a very expensive log archive. Hitachi Cyber sells the operational layer around the tools: the people, the tuned detections, and the response playbooks that turn signals into action.
For clients in operational technology - factories, grids, utilities - the stakes are different again. Industrial systems speak their own protocols and cannot simply be patched on a Tuesday. That is the specific gap the company's Poland SOC was built to close.
Round-the-clock monitoring, detection and response from a global SOC network, blending AI analytics with certified human analysts for rapid escalation.
Managed Detection & Response integrating SIEM, endpoint (EDR) and network (NDR) telemetry so threats have nowhere to hide between layers.
AI-driven analytics plus human insight to monitor an organization's digital footprint, anticipate risk and protect brand reputation.
Advisory across PCI, GDPR, privacy impact assessments, risk and control assessments - closing the gap between passing an audit and being secure.
Security posture assessments, penetration testing, vulnerability management, application assessment and incident response.
The MARS platform and Hitachi Data Center Analytics (HDCA) optimize performance and forecast capacity across multi-vendor storage.
The managed-security market is crowded. Hitachi Cyber's distinguishing features are less about a single feature and more about posture: platform-agnostic engineering, deep OT fluency, and the backing of an industrial parent.
Rather than lock clients into one stack, its engineers build custom connectors, detection rules and automated responses inside whichever SIEM the client runs - Google Security Operations, Microsoft Sentinel or Splunk. Being owned by Hitachi, a company that has built operational technology for a century, gives it a credible claim to defending the factory floor, not just the office network.
A five-country SOC network hands monitoring across time zones so coverage never sleeps. Each site plays a role; the Poland location is purpose-built for operational technology.
Hitachi Cyber runs a B2B managed-services model. Revenue is recurring - SOC and managed-detection subscriptions - supplemented by project-based advisory work (assessments, penetration tests, compliance) and platform-based analytics licensing.
Its expertise is operational and cross-domain. The company frames modern SOC monitoring around the "SOC Visibility Triad" - the idea that SIEM, endpoint and network detection each see what the others miss. It couples automated detection with human threat hunters, and it applies frameworks like MITRE ATT&CK to structure how attacks are anticipated. The unusual pairing of a security business with a performance-analytics business means the same organization thinks about both keeping systems safe and keeping them fast.

Krakow OT SOC opens with GlobalLogic (Jan); Sam Rehman named CEO (Dec).
In December 2025, Hitachi Cyber named Sam Rehman its Chief Executive Officer. Rehman brings more than 30 years in digital security and software; he previously served as CISO and head of the cybersecurity business at EPAM Systems.
Internally, his first moves signaled a transparency-first tone - he launched an "Ask Me Anything" series giving every employee unfiltered access to leadership. His mandate is growth across managed security, advisory, and OT/IT/AI security operations.
Hitachi Cyber competes in the global managed-security and MDR market against names like IBM Security, Accenture, Secureworks, Trustwave, NTT Security, Kudelski Security, Arctic Wolf and eSentire.
Its edge is not scale for its own sake but industrial context. A boutique MDR firm rarely speaks fluent OT; a hyperscale consultancy rarely delivers the follow-the-sun intimacy of a dedicated SOC network. Hitachi Cyber positions itself in between - large enough to run five SOCs and integrate with Google, Microsoft and Splunk, connected enough to the industrial world to defend the systems that run it.
It is a global managed security services provider offering 24/7 SOC monitoring, managed detection and response, cyber threat intelligence, GRC advisory and performance analytics.
Yes. It operates as Hitachi Systems Trusted Cyber Management Inc. within the Hitachi Group, delivering services under the Hitachi Cyber brand.
The global SOC network spans Canada, Switzerland, Japan, India and Poland, providing follow-the-sun 24/7/365 coverage.
Sam Rehman, a 30-year digital-security veteran and former EPAM Systems CISO, was appointed CEO in December 2025.
